1: Create a static library which exposes APIs
to manage snapuserd daemon.
2: Snapuserd daemon creates communication socket.
Bug: 168258493
Test: cow_snapuserd_test tests all the library API
along with the IO path from dm-snapshot.

The README.md states that this ordering is not guaranteed to give
flexibility for the future, however it's time to state that this
ordering is guaranteed, especially since:
1) We have a tests, EventTriggerOrder and
EventTriggerOrderMultipleFiles, which have guaranteed this ordering
since 2017.
2) We have users requesting and depending on this order
Also update some slightly out of date parts of the documentation:
1) We import /system/etc/init/hw/init.rc instead of /init.rc as the
first import
2) We additionally import /system_ext/etc/init and /product/etc/init
Test: n/a

These logs are not generally useful and can be considered to be spam
by some. Drop them to VERBOSE so that we can be selectively enabled
when debugging logd.
Test: these logs do not appears by default.

Implement OpenSnapshotWriter for non-compressed Virtual A/B. This is
done by adding an OnlineKernelSnapshotWriter class, which forwards all
writes to a dm-snapshot block device.
This also introduces a new ISnapshotWriter class which extends
ICowWriter, and adds features specific to libsnapshot (versus ICowWriter
which is intended only for the new COW format). The OpenSnapshotReader
call has been moved here since the writer retains all the information
needed to create the reader.
To test the new call, vts_libsnapshot_test has been modified to use
OpenSnapshotWriter.
As part of this change, all consumers of libsnapshot must now link to
libsnapshot_cow.

Once COWs are allocated, their size is fixed, and we don't want to
write beyond the end. To make this validation less tedious, the virtual
methods of ICowWriter have been made internal. The user-facing API calls
do validation before calling the internal variants.

adb has been built without -Wnon-virtual-dtor because Soong doesn't turn
the flag for the host targets, and the flag can't coexist with
-Wexit-time-destructors.
However, the new host target linux_bionic_arm64 turns the flag on,
because it inherits most of the cflags from the device config.
That is forcing us to implement the virtual destructor, which isn't
possible due to -Wexit-time-destructors.
Solving the issue by explicitly turning -Wnon-virtual-dtor off so that
it is disabled also for the linux_bionic_arm64 target.

This simplifies some of the logic and removes the need to pass an
Arch value to functions that should already know about the arch
it is operating on.
Includes fixes for debuggerd/libbacktrace.
Added new unit tests to cover new cases.
Test: All unit tests pass.
Test: Faked unwinder failing to verify debuggerd error messages display
Test: properly in backtrace and tombstone.
